PRISTINA, Kosovo — European Union’s enlargement commissioner is visiting Kosovo to try to push authorities to revoke a recent decision to impose a 100-percent tariff on goods from Serbia and Bosnia-Herzegovina.

Johannes Hahn met with Kosovo’s top officials Monday after earlier visiting Belgrade, where he held talks with Serbian President Aleksandar Vucic and called on Kosovo “to unblock regional cooperation and trade.”

Last month, Kosovo’s government imposed the tariff on Serbian imports saying it would stay in place until Serbia recognizes Kosovo’s independence and stops preventing it from joining international organizations.
